Summary:The Students will navigate another website on erosion with the help of a graphic organizer. I will explain that once sediment is removed and moves to another area in space it is considered eroded Then they will view a few short videos to examine the effects of erosion and weathering and determine which was happening in the video. They will also examine and think about management of erosion and what efforts people can do to combat erosion.
Objectives:
Students will understand and be able to identify different types of erosion.
Student will be able to explain the differences between weathering and erosion.
Students will be able to identify human attempts to combat erosion
Students will able to describe different environments in which erosion would be prominent.
Student will be able to compare and contrast weathering and erosion.
Students will be able to explain examples of erosion in their environments
Materials:
10-11 computers or classroom computer tied into the projector (if enough computers are unavailable)
projector ( that can be hooked up to a computer)
erosion student organizer
2 erosion clips which are downloaded to the teachers computer.
Instruction:
opening:
Explain that erosion is the movement of a piece of sediment from one place to another.
Ask the students what are examples of different types of sediment.
Ask the students, What type of force's on Earth could cause sediment to me eroded?
Instruct the students to work together in pairs to answer the questions
timing = 15 minutes
middle:
as the students are working in pairs to answer the questions, make sure you are walking around surveying the answers the students are writing down and are available for questions.
if student have questions try to use questioning to guide them to the right answer or to clarify information.
the organizer should take them about 15 to 20 minutes to complete.
Ask after what they thought the force was that shaped the cliffs in Hawaii? was it weathering or erosion? make sure they identify that some of it was, but most was because of enormous landslides.
Instruct the students to view video 2 by clicking on it on the same site.
following the video ask these questions: why doe the excessive rainfall increase the speed of erosion? What are the metal nets being laid down preventing, erosion or weathering? what are some other forms of management that could be used to prevent erosion.
timing = 30-35minutes
closing:
review the answers to the questions with the students by having the students explain what they thought the answer was.
explain to the students the project they will be starting during the next period, which involves adopting a body of water.
For homework have the students brainstorm a body of water they would like to research and what types of weathering and erosion occur around that body of water.
timing = 5-10 minutes
Notes:
prep time = 10-15 minutes
make sure the projector is set up and computers are available for the students. or you can also go over the erosion material through the projector.

- Instruct them to view video 1.
